In the present study, we determined levels of chlorinated pesticide residues in surface water samples collected from Charsadda district (KPK, Pakistan). SPME-GC-ECD with COMBI PAL CTC autosampler was used for extraction and analysis 20 organochlorine pesticides samples. For maximum efficiency SPME procedure, several parameters were studied, including desorption time fiber, solution pH, agitatio...

Agricultural use of organochlorine pesticides (OCPs) increased during the twentieth century but many them have been progressively banned several decades after their introduction. Nevertheless, these lipophilic chemical compounds may persist in soils and sediments. From sediment deposits, it is possible to reconstruct chronology OCP releases relation former applications through time. long-term f...

To assess organochlorine compound (OC) contamination, its possible sources, and adverse health impacts on giant pandas, we collected soil, bamboo, panda fecal samples from the habitat research center of Qinling (Ailuropoda melanoleuca qinlingensis)—the rarest recognized subspecies. The polychlorinated biphenyls (PCBs) pesticides (OCPs) concentrations were comparatively low which suggests that m...

Man depends heavily on pesticides to boost his agricultural productions. This study aimed at carrying out a risk assessment of pesticide residues in samples beans stored and sold Wukari Town, Nigeria. Different were collected randomly from different market points within Wukari, Rafin kada Idofi. The residue analysis was carried using GC/MS after sample extraction, filtration Concentration. mean...

The low yield of food production ascribed to harm caused by pests has led the application pesticides crops. Pesticide residues from on crops are mostly found in foods that can cause diseases for consumers such products. A total 37 pesticide consisting 15 organochlorines (OC), 13 organophosphorus (OP) and 9 synthetic pyrethroids (SP) were determined. QuEChERS method was exploited extraction clea...

Brazil has experienced a rise in the use of agrochemicals recent years, representing potential threat to nearby ecosystems. The Volta Grande Reservoir (Minas Gerais/São Paulo, Brazil) about 87% its area surrounded by agricultural systems, and many compounds used agriculture end up being carried into water bodies. Given ecological risk, our purpose was assess pesticides reservoir. We collected s...
